| U2 Series Straigh-Through Silencer | 
          
            |  The U2 Series is an economical straightthough silencer for applications requiring lower-degree noise attenuation. It is fundamentally similar to the U5 Series, but has lesser attenuation due to its relatively low length to diameter ratio. Mild steel construction, primer-coated exterior. |
